Getting starting

I am new to this newsgroup and apologize in advance if this has been
discussed already. I would like to get started growing edible
mushrooms and am wondering if someone can recommend some good books to
help me get started.
In addition to general information, I would like to know if mushrooms
which are commonly grown commercially would grow well in colder
climates. I have a house in northern Vermont although now I spend
most of my time in Ithaca, NY since my wife is a student there.
Any help would be appreciated. Ned
